Which feature do prokaryotic and eukaryotic cells share?

They have multiple features in common. They share basic cell features such as cell membranes and molecules, such as proteins, lipids, and even carbohydrates.

All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.
